Autosorb - Model iQ/MP-XR - Gas Sorption Analyzers
A highly sophisticated gas sorption analyzer available with up to three physisorption analysis ports for surface area analysis and pore size measurements, two of which can be equipped for low pressure micropore analysis including optional 0.1 torr transducer(s) (see XR models).
One port is available as a chemisorption station, complete with a high temperature furnace coupled with fan-assisted cooling. The chemi- version is also offered with optional flow-based measurement capabilities (TPX, pulse titration). The chemi station retains full physisorption capability.
A vapor dosing option is available for both physi - and chemi-units and features a 50oC thermostatted manifold chamber.
Models are available with up to four built-in degas ports (turbo pumped vacuum is standard on the MP and C models) and feature computer-controlled ramp/hold/test protocols, a dedicated cold-trap, and optionally a second (dedicated) vacuum system. This eliminates the need to degas on the analysis stations thus preventing contamination of the analysis section.
The host of models, options, accessories, configurations and upgradeability make the Autosorb-iQ the most advanced instrument of its type available today, with a single PC being able to control up to 4 autosorb-iQ units.
Universal cryo-cooling accessory to gas sorption analyzers, capable of enabling 50+ hour sample analyses at temperatures in the range of 82 to 115K with ±0.005K accuracy. Ideal for performing the most scientifically reliable micropore-mesopore and hierarchical pore structure characterizations with argon gas at 87.3K, according to the latest IUPAC recommendations (Thommes et al., Pure Appl. Chem. 87(9-10), 1051-1069 (2015)), but using liquid nitrogen instead of liquid argon or more involved alternatives. more.
Sub-ambient temperature physisorption measurements at temperatures other than those of liquefied gases (e.g., LN2, LAr) are important for studying gas storage and separation using structured porous materials. This powerful and precise thermostat affords isotherm measurements from 20K up to 320K without liquefied gases or additional heating devices.
For measurements at, or around, room temperature (e.g., vapor sorption studies with vapor option, or CO2 at OoC) chiller / heater / circulators are available. more...
Heats of adsorption are another important parameter associated with state-of-the-art applications using porous materials. These enthalpies can be measured calorimetrically using this accessory to interface the iQ to a third-party calorimeter.
The capability of the 'Chemi' model is greatly enhanced by the addition of a quadrupole mass spectrometer (QMS). This accessory is 'close-coupled' and requires no additional bench-space, and is just as capable but much more cost-effective than a separate stand-alone QMS system.
